The routine was inspired by enom workouts. This upper body routine that mixes pulling and pushing your own body weight. This routine can help you when you have minimal equipment. You only need a bar to do pull ups and the floor. The workout consists on doing 20 pull ups and 20 push ups in one minute or less, then you'll have 1 minute rest. Next you'll do 18 pull ups and 18 push ups in one minute or less, if you can, and so on and so forth. You'll perform 2 pull ups less as well as 2 push ups less. When you reach 10 push up and 10 pull ups you'll start increasing 2 push ups and 2 pull ups per round again but you'll have 2 minutes do do it and 2 minutes rest. The routine is sure to be intense and it only takes about 30 minutes. You can vary the style of you push ups and pull ups to make it a bit more interesting as long as they are done with proper form. For example you can try to do some diamond push ups, or some close grip pull ups to target more the biceps in some rounds. Have fun with it and build crazy endurance. You can split the number of reps as you like, for example, you can do 16 pull ups first then the 20 push ups and come back to finish 4 pulls at the end. The goal is just to get all the reps under 1 minute for the first superset and under 2 for the second superset. You might want to set a timer so you make sure you are doing the exercises within the interval permitted.
